Abstract
The utility model belongs to the technical field of wind power generation technologies and discloses a wind driven generator. The wind driven generator comprises blades, a transmission shaft and a generator rotor, wherein the blades are connected with the transmission shaft, and the transmission shaft is connected with the generator rotor through a speed changing box. The wind driven generator further comprises a controller, wherein the controller controls the gear transmission ratio of the speed changing box and enables the rotation speed output to the generator rotor to be a preset value. The wind driven generator outputs constant voltage through conversion of the speed changing box.
Description
Technical field
The utility model belongs to technical field of wind power generation, particularly a kind of wind-driven generator.
Background technique
Wind-power electricity generation machine technology is more and more paid attention to as a clean energy technology, and in wind-power electricity generation research field, effective utilization of wind energy, the conversion of electric energy etc. are always as the main direction of studying.Due to the irregularities of wind energy, make the amplitude of variation of output voltage quite large, therefore, its output voltage can not directly apply to load.
Therefore, existing wind-driven generator is generally all by after being electric energy by wind energy transformation, with the form of chemical energy, is stored in storage battery.
How wind-driven generator can export voltage stabilizing electricity, is the blank of wind-power electricity generation research field always.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of wind-driven generator, to by the adjusting of transmission gear shift, realizes the voltage of stable output.
The technological scheme that the utility model is taked is:
A kind of wind-driven generator, comprise fan blade, transmission shaft and generator amature, it is characterized in that, described fan blade is connected with described transmission shaft, between described transmission shaft and described generator amature, by gearbox, be connected, described wind-driven generator also comprises controller, and the rotating speed that the gear ratio that described controller is controlled described gearbox makes to export to generator amature is a default scope.
Further, described gearbox is realized the conversion of velocity ratio by the gear of change different-diameter.
Further, described controller is connected with the voltage output end of described wind-driven generator, and described controller is determined the gear of changing corresponding diameter according to the voltage of described voltage output end.
The beneficial effects of the utility model are:
(1), by the conversion of gearbox, export the voltage of constant scope;
(2) output can directly apply to load;
(3) controller judges that according to voltage output value the speed change of carrying out gear-box regulates, and precision is high.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model wind-driven generator;
Accompanying drawing 2 is module frame charts of the utility model wind-driven generator.
Label in accompanying drawing is respectively:
1. fan blade; 2. transmission shaft;
3. gearbox; 4. generator amature;
5. generator; 6. controller.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model wind-driven generator is elaborated.
Referring to accompanying drawing 1, wind-driven generator comprises fan blade 1, transmission shaft 2, gearbox 3 and the generator amature 4 connecting successively, and generator amature 4 carries out cutting magnetic line and produces electric energy in generator 5.Gearbox 3 is speed-changing gear box, and its input speed speed change being exported by output shaft after gear rotates, switches the driving cog of different-diameter in gearbox, makes in the different situation of input speed, and the rotating speed of output shaft is in a default scope.
Referring to accompanying drawing 2, wind-driven generator realizes by controller 6 control that gear-box 3 is switched to speed change gear, and controller 6 is connected to the voltage output end of generator 5.Controller 6 is determined the gear of changing corresponding diameter according to the voltage of voltage output end.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
